I'd classify the current behavior as a serious usability issue. Here is why:

  • Most users are happy with the default transformations. (I assume that's the case because it's not often a topic in the support channels.)
  • It adds at least two more clicks for opening a layer (if it has to be transformed).
  • Opening old project files is a real pain (until you notice and decide to use "remember selection").
  • Many users have no idea what to do with the dialog. It's just a list of weird parameters which most have never seen before. You only get some information about "preferred" and "deprecated" transformations on mouse-over.
  • Hiding deprecated transformations does not seem to work currently (tested with nightly on Windows 7).
  • Users who need non-standard transformations could add them to their QGIS options.
  • I think we would just scare away users if the first thing they see when they try to load some dataset is this dialog.
